The results showed that different southernwood cultivars displayed different artemisinin contents, especially, the artemisinin contents of planting cultivars and the cultivars with coloured stem were higher. Further AFLP analysis indicated that a specific fragment was amplified respectively with the primers of EA04-MC05 and EA01-MC01. According to the differentia fragments, we clustering analyzed the 10 major kinds of southernwoods by utilizing WPGMA approach. However, there was no distinctly relativity between the artemisinin contents and diversity of AFLP analysis and just can distinguish, southernwood of Youyang county from Shapingba and Beipo in producing area which still illuminated that the heredity differentia of southernwood presented itself obviously in different area.

研究结果表明：不同的青蒿株系青蒿素含量不同，栽培株系和色茎株系青蒿素含量较高；进一步的AFLP分析表明引物组合EA04-MC05和EA01-MC01分别在高产青蒿株系和茎色青蒿株系中均能扩增出一条特异性条带；根据AFLP差异带，用WPGMA法对10个主要青蒿类型进行聚类分析，结果没有得到与青蒿素含量的明确关联，只是从产地上将酉阳青蒿与北碚、沙坪坝青蒿区分，说明不同地区青蒿的遗传差异较大。

The results demonstrated closer relationship between the two species, in accordance with those from morphological classification. That is to say, the taxon of Helice is divided into two subgenera, Helicana H. japonica and H.

由于仿厚蟹亚属和厚蟹亚属的蟹类在外形上的差异较大，而且本研究的分子数据也表明二者之间存在着很大的遗传差异，因此，建议将此2亚属提升为属。

On the aspect of urban spatial distribution DM: Adopting the conception model of combination of location and attribute, the author brings spatial coordinates, spatial relationship and attribute character into the unitive model of spatial computation, studies city's land suitableness evaluation and the method of spatial clustering in division of urban function districts and brings forward the arithmetic of classification layer. Aiming at land spatial optimization allocation, the author puts forward SGA. In this arithmetic selection, crossover and mutation operator are progressed on the space.

在城市空间分布数据挖掘方面：采用空间—属性一体化概念模型，把空间坐标、空间关系和属性特征纳入到统一的空间计算模型，分别对城市土地适宜性评价和城市功能区划分中的空间聚类方法进行了研究，并提出了一种分类图层的平滑算法；针对城市土地的空间优化配置，提出了一种空间遗传算法，该算法中的选择、交叉、变异算子都是在空间上进行的；对多要素离散空间场之间的相关性测度，定义了一种基于信息熵的规范的相关指数，并给出了计算方法。

DNA polymorphic fragments were obtained by simultaneous RAPD amplification of both symbiont and host.

通过建立满江红鱼腥藻及其宿主的UPGMA聚类关系图，看出二者在遗传分支上存在着一定程度的协同对应关系。

在水稻上，为了获得这类遗传材料，从中籼3037同源三倍体后代产生的非整倍体中，在筛选初级三体的同时，进行了等臂染色体变异材料的筛选。

Results The genetic variability among trypanosome isolates examined was obvious with an average genetic distance of 41.2%（ranged from 0 to 100%）.

方法利用移动遗传因子-PCR技术对26个锥虫虫株基因组进行扩增，同时利用邻位相连法对扩增产物进行聚类分析。

Should be long, strong and deep right to the end of the muzzle, but not coarse. Full face it should be oval in outline and be filled completely up giving the impression of fullness with a surface devoid of hollows or indentations, i.e., egg shaped. In profile it should curve gently downwards from the top of the skull to the tip of the nose. The forehead should be flat across from ear to ear. The distance from the tip of the nose to the eyes should be perceptibly greater than that from the eyes to the top of the skull. The underjaw should be deep and well defined.Should be clean and tight.

18世纪时，用牛头犬与梗类配种产生叫"bull and terrier"的牛头梗斗犬，后来与英国的玩具梗和惠比特犬品种，产生出具凶猛性，快速敏捷的犬种来。1860年，犬商詹姆士喜克斯将此犬加上英国猎梗，大麦町犬，西班牙波音达的品种，经过多次品种改良后，产生了现在的白色，平脸，强壮，四肢比祖先短小的牛头梗。1920年，因为白色品种遗传了听觉上的缺陷，被毛被加上了其他颜色。19世纪，白色牛头梗在热爱斗牛犬的人中间深受好评。

Study on clinical character and genetic model of Dyschromatosis Symmetrical Hereditaria and Freckle Pigmentary inherited disease, which occupies a part of population in genodermatosis, is disease of monogenic inheritance. The genes of some diseases have been identified, such as Xeroderma, incontinentia pigmentation and PJS syndromes.

色素性遗传性疾病在遗传性皮肤病中占有不小的比重，这类疾病大都属单基因遗传病，而且有些疾病的遗传基因已经被找到，如着色性干皮病、色素失禁症、PJS综合症等。

Maximum parsimony tree constructed by using 42 capra hircus from 16 breeds, 11 wild capra from 7 species and sheep used as outgroup. The results showed that domestic goats and wild capra existed differently branches except Capra aegagrus.

用绵羊作为外群，16个家养品种的42条细胞色素b序列以及7个野生种的11条序列构建了系统发育MP树，结果表明除角〓羊外，家山羊、野生山羊分别聚在不同的枝上，但在家山羊群体内部出现了遗传分化，本实验中测定的所有家山羊个体聚为3大类。

According to sequence cluster analysis of the the tested samples, it indicates that the gene distance of RKN-9, RKN-8, RKN-21, RKN-11, RKN-18 , RKN-20, RKN-17, RKN-22, RKN-23, RKN-24 and RKN-25 to Meloidogyne incognita and Meloidogyne arenaria was very close with homology of 100% and 99%, respectively.

根据25个根结线虫种群序列比对分析和聚类分析可知，河北廊坊的番茄根结线虫、安徽宿州的黄瓜和番茄根结线虫、安徽太和的桔梗根结线虫、安徽和县的番茄根结线虫、浙江杭州的黄瓜根结线虫、四川成都的番茄根结线虫、安徽泗县的黄瓜根结线虫和中国农业大学四个不同番茄品种上的根结线虫的序列之间同源性为100％；它们与花生根结线虫和南方根结线虫(M.incognita)的遗传距离最近，序列同源性分别达到100％和99％。
